Which term refers to the horizontal angle or direction of a line relative to true north?

• A. Azimuth
• B. Elevation
• C. Pitch
• D. Bearing

Answer: (A)

Azimuth is the horizontal angle or direction of a line relative to true north. It’s the compass direction in the horizontal plane, measured in degrees clockwise from true north (0° is north, 90° is east, 180° is south, 270° is west). This concept is used when you need a precise horizontal direction for alignment or navigation. Elevation is the vertical angle above the horizon, not the direction on the compass. Pitch describes tilt along the forward–backward axis, common in aircraft or rotating equipment. Bearing refers to the direction from one point to another and can be relative to true or magnetic north; the specific horizontal direction relative to true north is best described as azimuth.
